Capcom is throwing an Easter sale, and it has slashed the price of some of its most popular games on iOS to just $0.99. So if you’re a fan of Street Fighter or Mega Man,now’s the time to pick up a bargain that’ll keep you entertained over the Easter weekend.

Street Fighter and Tekken are ready to go head-to-head on iOS in this “never-before-dreamed-of-crossover battle,” Street Fighter X Tekken. Now available to download from the App Store, the game brings online multiplayer brawling to iOS with 3D visuals optimized for your Retina display.

Following the start of EA’s iOS sale yesterday, which has seen popular titles like FIFA 12, Dead Space, and Need for Speed reduced to just $0.99, other iOS developers are now throwing their hats into the ring. We got a list of titles from Sega, Capcom, Warner Bros. and more that are now on sale for July 4. Come and get ’em while they’re cheap.

Forget stunning 3D graphics and fancy gesture-based gameplay; good, old-fashioned 2D arcade fighters are still some of the most entertaining games money can buy. And Marvel vs. Capcom 2is the latest addition to that genre on iOS. It’s one of the most popular fighting games of all time, featuring 56 legendary characters and an insane, tag-team fighting experience.

This is great. Japanese games giant Capcom has slashed the price of Street Fighter IV for iOS to just one dollar (59p in the UK) until March 22nd. Sega is doing something similar for Sonic the Hedgehog and Sonic 2.

Every penny from those sales will be donated to relief funds for the victims of the Japanese tsunami and earthquake. Street Fighter has already knocked Tiny Wings off the top of the UK Top 25 list as a result.

Capcom says: “We can never thank you enough for all the support each one of you are giving to us. People from all over the world, please unite with us to help people in the disaster-struck area.”

You heard ’em, kids. Grab your bargains now, and send a dollar to help people who need it.
